Application June 22, 1939, Serial N0.v 280,648

4 Claims. (,Cl. 36-59) This invention relates to shoes for athleticpurposes and has for its primary object to provide improved pegs orcleats therefor, and improved means for anchoring the pegs and cleats ina manner such that the presence thereof enhances, rather thanembarrasses, movement of the athlete. This invention is similar, in somerespects, to my co-pending application Serial No. 270,613, filed April28, 1939.

The main object of this invention is similar to that of the co-pendingapplication above referred to in that it relates to the provision ofpegs or cleats on athletic shoes and aims to reduce the hazard resultingfrom the persence of such pegs, both as to the wearer or otherscontacted thereby. In this respect a metal peg having an elastic sheathis provided.

Another object is to provide an athletic shoe having a sole composed offore and heel portions connected by a shank, the fore and heel portionshaving a bendable plate imbedded therein and rendering them lessflexible than normally, and the shank having a plurality f slits thereinrendering it highly flexible in one direction of bending withoutmaterially altering its flexibility in the other direction. In thisrespect the invention teaches alternative bendable plate constructions.According to the invention the bendable plate may be formed of a singlepiece of comparatively thin sheet metal having apertures for thereception of peg anchoring elements, it may be of non-corrosive plasticmaterial reinforced by imbedded metal strips or imbedded cord-likematerial, or it may be of sheet metal sections having complenientalbifurcations of such a substantial length that the joint between thesection permits lengthwise eXtension without weakening the platenoticeably on any single transverse line.

Another object is to provide interengaging elements clamping a portionof the sole and the bendable plate in interposed relation therebetweenand having means for removably anchoring pegs thereto. In this respectthe invention provides two disc like elements having interengagingscrew-threaded portions for drawing the two discs together. One elementengages the bendable plate imbedded in the sole, the other elementengages the outside surface of the sole, and the peg has a screwthreadedstem which interengages with a screwthreaded portion of one of saidelements.

Another object is to provide a disc like element of the character abovereferred to having a portion shaped to coact with the walls of similarlyshaped apertures in thev bendable plate to prevent rotation of theelement.

Another object is to provide a disc like element of the character abovereferred tol having prongs struck therefrom and imbedded in the sole toprevent rotation thereof. In this respect a more specific object is toprovide the pegs with yielding projections adapted to engage in theapertures formed by striking the prongs inwardly to prevent accidentalrotation of the pegs which are screwthreaded into the anchoringelements.

Another object is to provide a peg comprising a metal Core member havinganchoring means, a base'portion, a post adapted to penetrate the gorund,and an elastic sheath around the base portion and post, and secured withrespect to the base portion only. To this end the base portion is coppercoated in order that the sheath, which is of rubber or the equivalent,will be surface bonded thereto by vulcanizing the rubber.

Another object is to provide a peg which is reinforced to resist wearand destruction through rough usage, an example of said rough usagebeing use on frozen ground as commonly occurs in football games.Alternative reinforcing means are contemplated according to theinvention which discloses a metal washer-like element disposed at theextremity of the elastic sheath or imbedded in the elastic sheath,unsecured with respect to the metal post, or a layer of cord-likematerial impregnated with rubber and constituting a wear resistantsurface.

Other objects and advantages will become more fully apparent asreference is had to the accompanying drawing wherein my invention isillustrated, and in which:

Fig. 13 is a section taken on the line |3-I3 of Fig. 12,

Fig. 14 is a section of the peg shown in Fig. 11,

Fig. 15 is a plan of one of the peg anchoring elements of Fig. 11, and

Fig. 16 is a plan o the peg.

Referring to Figs. l and 2, Ia designates a sole having a fore part Iand a heel part 2 connected by a shank 3. The shank 3 has a plurality oftransverse slits l rendering it highly flexible in one direction ofbending, without noticeably affecting its flexibility in the 'otherdirection. Secured to the fore part I is an outer solen5, and secured tothe heel portion 2 is an outer sole 3. Resting on the fore part I of thesole is a thin metal plate 'l and resting on the heel portion 2 is athin metal plate 8, both plates being covered by an insole 9.

The plates 'I and 8 provide anchorage for pegs or cleats in a mannerhereinafter described, but their presence regardless of this purposeprovides fore and heel portions which, although capable of bending, haveless flexibility than normally is the case. The fore part and heel partwhich are comparatively stiff, in combination with the shank portion 3which is highly flexible, provide a sole which is comfortable to anathlete, and which enhances, rather than embarrasses, movement of thefeet.

As shown in Fig. 2, the bendable plate may be formed of a plastic whichis non-corrosive under the conditions expected during use of a shoe. Inthis case, the sheet I has metal strips Ii imbedded therein to providethe desired degree of nexibility. As a further alternative, cord-likeelements I2 may be imbedded in the sheet lila to comprise the solereinforcing means therefor, or they may, if desired, be used inconjunction with strips such as shown in Fig. 4.

In Fig. 6, the bendable plate is shown as formed in two sections I3 andIll having complemental bifurcations I providing a plurality ofjuxtaposed ngers. The plate when so constructed is capable of lengthwiseextension and is of substantially constant flexibility throughout itsentire length.

Fig. 7 illustrates in detail the attachment of any one of the pegs I8 tothe plates 1 or 8. As shown, a disc-like element I'I bears on the plateI or S and has an angular portion I8 extending into a similarly shapedopening I9 in the plate to prevent rotation of the element I1. Aninternally threaded stern 20 on the element Il receives a screwthreadedstem ZI, and integral with the stem EI is a base portion 22 with a post23 projecting outwardly therefrom. Surrounding the base 22 and the post23 is an elastic sheath 2li having a metal ring or washer-like element25 imbedded therein.

The base portion 22 is preferably copper coated so that when the sheath2li, which is formed of rubber, is vulcanized therearound, it willadhere thereto. The rubber 2li and the reinforcing ring 25 are unsecuredWith respect to the post 23 so that when the peg is placed in contactwith the ground the sheath may be compressed to expose the peg. Thus,the post 23 penetrates the ground, while the sheath merely pressesagainst the ground.

Fig. 8 illustrates a metal ring or washer-like element 25a secured tothe outer extremity of the elastic sheath 24a, unsecured with respect tothe post 23a. The presence of the rings 24 and 24a, either imbedded orexposed, increases the useful life of the rubber sheath.

As shown in Fig. 9, the screwthreaded stem Il and the anchoring elementI1 may be dispensed with, to provide a less expensive construction, bythe provision of rivet-like arms 26 on the metal peg core 21. The arms26 extend through the sole members 28 and are bent over into engagementwith the bendable plate 29.

In Fig. 10 there is shown a peg having a metal core with an encasinglayer 3| of rubber. On the outer extremity of the rubber 3| is a layer32 composed of rubber impregnated cord-like material which constitutes awear resistant surface.

In Figs. 11 to 16 there is shown a construction embodying a disc likeelement 33 having an internally and externally threaded stem 34 integraltherewith. The stem 33 projects through a bendable plate 35 and the solemembers 3'6, and is held against rotation by an angular portion 31 whichengages the Walls of a similarly shaped opening 38 in the plate 35. Adisc like element 33 has an internally threaded stem ll screwed onto theexternal threads of the stem 33, and has prongs 4I struck inwardlytherefrom after it is screwed into place to hold it against removal.

A peg having a threaded metal stem 42 and an elastic sheath 63 is placedwith its stem engaging the internal threads of the stem 33. Integralwith the sheath I3 are projections 44 which engage in the apertures I5formed by striking the prongs Il inwardly, and function to yieldinglyoppose removal of the pegs.

What is claimed is:

1. A peg comprising a metal element having anchoring means and a post,an elastic sheath around said post, and a reinforcing element secured tothe sheath and unsecured with respect to the post, said reinforcingelement having an opening through which said post is adapted to projectwhen the sheath is compressed.

2. A peg comprising a metal element having anchoring means and a post,an elastic sheath around said post, and a reinforcing element secured tothe sheath and unsecured with respect to the post, said reinforcingelement comprising a metal washer on the outer extremity of said sheath.

3. A peg comprising a metal element having anchoring means and a post,an elastic sheath around said post, and a reinforcing element se curedto the sheath and unsecured with respect to the post, said reinforcingelement comprising a metal washer imbedded in the elastic material.

4. A peg comprising a metal element having anchoring means and a post,an elastic sheath around said post, and a reinforcing element secured tothe sheath and unsecured with respect to the post, said reinforcingelement comprising a layer of wear resistant material at the extremityof said sheath, said reinforcing element havlng an opening through whichsaid post is adapted to project when the sheath is compressed.
